Asp.Net MVC+BootStrap+EF6.0实现简单的用户角色权限管理6

接下来先做角色这一板块的（增删改查），首先要新建一个Role控制器，在添加一个RoleList的视图。表格打算采用的是bootstrap的表格。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace AuthorDesign.Web.Areas.Admin.Controllers
{
    public class RoleController : Controller
    {
        //
        // GET: /Admin/Role/

        public ActionResult RoleList()
        {
            return View();
        }

    }
}

在当我做查询的时候返现角色少了个排序，也可以说是角色的等级吧，也可以就是用来排序用的。那么老方法先在AuthorDesign.Model.Authory这个类下面新增一个属性

        /// <summary>
        /// 排序数字
        /// </summary>
        public int OrderNum { get; set; }

然在打开控制台选择DAL然后输入add-migration AddAuthoryOrderNum 完成之后再次输入update-database即可。

然后在Model下建立一个ParamModel，这是专门用来接收分页信息的。

#region 分页基类
    /// <summary>
    /// 分页基类
    /// </summary>
    public class ParamModel
    {
        /// <summary>
        /// DataTable请求服务器端次数
        /// </summary>       
        public string sEcho { get; set; }

        /// <summary>
        /// 每页显示的数量
        /// </summary>
        public int iDisplayLength { get; set; }

        /// <summary>
        /// 分页时每页跨度数量
        /// </summary>
        public int iDisplayStart { get; set; }
    }
    #endregion

然后在建立一个RoleParamModel，继承下ParamModel，

#region 角色分页
    /// <summary>
    /// 角色分页
    /// </summary>
    public class RoleParamModel : ParamModel
    {
        /// <summary>
        /// 是否根据排序字段进行倒序排列
        /// </summary>
        public bool IsDesc { get; set; }
    }
    #endregion

接下在AuthoryRepository这个下面写一个获取权限分页的方法

        /// <summary>
        /// 获取角色分页列表
        /// </summary>
        /// <param name="startNum">起始数字</param>
        /// <param name="pageSize">页长</param>
        /// <param name="isDesc">是否倒序排列</param>
        /// <param name="rowCount">总页数</param>
        /// <returns>角色分页列表</returns>
        public IQueryable<Authory> LoadPageList(int startNum, int pageSize, bool isDesc, out int rowCount) {
            rowCount = 0;
            var result = from p in db.Set<Authory>()
                         select p;
            if (isDesc) {
                result = result.OrderByDescending(m => m.OrderNum);
            }
            else {
                result = result.OrderBy(m => m.OrderNum);
            }
            rowCount = result.Count();
            return result.Skip(startNum).Take(pageSize);
        }

我可能实现的方法写的不好，如果有什么地方需要改进的麻烦你们告诉我下。

然后再去IAuthoryRepository这个接口上定义下规范

        /// <summary>
        /// 获取角色分页列表
        /// </summary>
        /// <param name="startNum">起始数字</param>
        /// <param name="pageSize">页长</param>
        /// <param name="isDesc">是否倒序排列</param>
        /// <param name="rowCount">总页数</param>
        /// <returns>角色分页列表</returns>
        IQueryable<Authory> LoadPageList(int startNum, int pageSize, bool isDesc, out int rowCount);

接下来就是前台的调用了，在Role控制下添加一个返回JsonResult的方法

        public ActionResult RoleList()
        {
            return View();
        }

        [HttpPost]
        public JsonResult RoleList(Models.RoleParamModel model) {
            int rowCount = 0;
            var result = EnterRepository.GetRepositoryEnter().GetAuthoryRepository.LoadPageList(model.iDisplayStart, model.iDisplayLength, model.IsDesc, out rowCount);
            return Json(new {
                sEcho = model.sEcho,
                iTotalRecords = rowCount,
                iTotalDisplayRecords = rowCount,
                aaData = result
            }, JsonRequestBehavior.AllowGet);
        }

先对RoleParamModel这个类解释下，这类里面有四个属性，分别是

        /// <summary>
        /// DataTable请求服务器端次数
        /// </summary>       
        public string sEcho { get; set; }

        /// <summary>
        /// 每页显示的数量
        /// </summary>
        public int iDisplayLength { get; set; }

        /// <summary>
        /// 分页时每页跨度数量
        /// </summary>
        public int iDisplayStart { get; set; }
        /// <summary>
        /// 是否根据排序字段进行倒序排列
        /// </summary>
        public bool IsDesc { get; set; }

sEcho是jquery.dataTables这个插件在与后台进行交互的时候会自动传过来的（aData里面可以获取到的）；iDisplayLength与iDisplayStart也是同样可以获取的到的，然后IsDesc这个字段用来表示用户是选择按照排序字段正序排序还是倒序排序用的。下面给上我的前台代码：

@section Header{
    <style type="text/css">
        /*加载动态图片*/
        .dataTables_processing {
            position: absolute;
            top: 50%;
            left: 50%;
            width: 100%;
            height: 40px;
            margin-left: -50%;
            margin-top: -25px;
            padding-top: 20px;
            text-align: center;
            font-size: 1.2em;
            /*background-color: white;*/
        }
    </style>

            });
            $("#sample-table-2_filter").html("");//移除自带的搜索
        })
    </script>
}

前台代码主要是jquery.dataTables的使用，我对jquery.dataTables获取那个特定字段的排序还不是很清楚，只能通过遍历下bStorable里面的内容去获取。下面稍微解释下前台代码

 "sAjaxSource": "/Admin/Role/RoleList",这个主要定义下服务请求的路径。aoColumns：这下面主要是设置列的信息与样式用的。

"fnRowCallback": function (nRow, aData, iDisplayIndex) { /* 用来改写指定行的样式 */
$('td:eq(0)', nRow).html("<label><input type=\"checkbox\" class=\"ace\" value=\"" + aData.Id + "\"><span class=\"lbl\"></span></label>");
return nRow;
}

这代码主要用来改写指定行的样式，比如第0行就把他改为了选择框的样式。

这里是jquery-datatables的一些信息，可以自己去看下。$("#sample-table-2_filter").html("");//移除自带的搜索  这段代码主要是为了移除掉原来他自带的搜索框，你可以先去掉看下效果然后再加上。下面放上页面的显示效果

那么做了列表之后接下来就是对权限的增加与修改了。下面是Role控制器的全部代码，里面包括了修改，删除，增加，更改角色状态

                    });

在做修改的时候我碰到了Attaching an entity of type 'AuthorDesign.Model.Authory' failed because another entity of the same t这个问题，大概意思就是说你在修改的时候context还包有一个相同主键值的，随意不能进行修改。修改方法参照这个网址http://www.cnblogs.com/scy251147/p/3688844.html，这里说的很详细。顺便添上我RoleList的整个页面代码

页面代码上需要注意的是我在添加修改和删除这里分别加上了AddRole和UpdateRole和DeleteRole,这是为了方便下面可以使用。

在做修改的时候，ajax需要把每个字段都要重新赋值一边给文本框，问下你们有没有简单的方法，除了用Angularjs和KO框架之外。知道麻烦告诉我下啊。
